Comparison of the serum neutralization test and a competitive enzyme-linked immunosorbent assay for the detection of antibodies to vesicular stomatitis virus New Jersey and vesicular stomatitis virus Indiana.

A competitive enzyme-linked immunosorbent assay (C-ELISA) for the detection of antibodies against vesicular stomatitis virus New Jersey (VSV-NJ) and vesicular stomatitis virus Indiana (VSV-IN) was compared with the serum neutralization test (SNT) using 1,106 serum samples obtained from dairy cattle on sentinel study farms in the Poás region of Costa Rica. Kappa coefficients between the C-ELISA and the SNT were 0.8871 (95% confidence interval [CI]: 0.8587-0.9155) and 0.6912 (95% CI: 0.6246-0.7577) for the VSV-NJ and VSV-IN tests, respectively. These results indicate good to excellent agreement between the 2 tests under these conditions.

Neutralizing antibodies against vesicular stomatitis viruses (serotypes New Jersey and Indiana) in horses in Costa Rica.

Serum samples were collected from domestic horses in 4 different regions of Costa Rica to detect antibodies against vesicular stomatitis viruses, serotypes New Jersey (VSV-NJ) and Indiana (VSV-IN). A total of 214 samples were tested by the virus neutralization test. The sampling regions were identified as low North Pacific dry area (1), low Middle Atlantic humid area (2), low South Pacific humid area (3), and the highlands (4). In region 1, 97.1% of horses were positive for VSV-NJ and 16.5% were positive for VSV-IN. The mean antibody titer and its standard deviation after logarithmic transformation were 5.86 +/- 0.9 for VSV-NJ and 3.55 +/- 1.66 for VSV-IN for region 1. In region 2, 40.7% of horses were positive for VSV-NJ and 32.2% were positive for VSV-IN. The mean antibody titer in region 2 was 4.33 +/- 1.82 for VSV-NJ and 3.47 +/- 1.73 for VSV-IN. In region 3, 20.79% of horses were positive for VSV-NJ and 27.6% were positive for VSV-IN. The mean antibody titer in region 3 was 4.39 +/- 1.89 for VSV-NJ and 3.47 +/- 1.82 for VSV-IN. In region 4, 91.3% of horses were positive for VSV-NJ and 73.9% were positive for VSV-IN. The mean antibody titer in region 4 was 5.77 +/- 1.10 for VSV-NJ and 4.85 +/- 1.63 for VSV-IN. This is the first published report of the detection of virus-neutralizing antibodies against VSV-NJ and VSV-IN in horses in Costa Rica.

A single-tube multiplex reverse transcription-polymerase chain reaction for detection and differentiation of vesicular stomatitis Indiana 1 and New Jersey viruses in insects.

A multiplex single-tube reverse transcription-polymerase chain reaction (RT-PCR) has been developed for the detection and differentiation of vesicular stomatitis viruses (VSV), Indiana 1 and New Jersey, from insect samples. Using this assay, detection of either or both viruses in as little as 20 fg of total RNA from tissue culture was achieved, along with detection of vesicular stomatitis (VS) RNA from macerates containing 2 infected mosquitoes in pools of 10-30 noninfected mosquitoes. Vesicular stomatitis virus was detected by RT-PCR in all culture-positive samples, and detection as low as 4 plaque forming units per milliliter was achieved. Comparison between RT-PCR and tissue culture revealed that RT-PCR was able to detect VSV in a volume of insect macerate averaging almost 100 times less than that required for detection by tissue culture. The reported RT-PCR is a potential valuable tool for rapid and sensitive detection and differentiation of VS in insects because intense work associated with viral isolation, the cytotoxicity of insect extracts, and separate virus identification steps can be avoided. Potential application to detection and differentiation of VSV serotypes from vertebrate hosts is addressed.

Salvage chemotherapy in patients with extragonadal nonseminomatous germ cell tumors: the Indiana University experience.

PURPOSE: Patients with relapsed extragonadal germ cell tumors (EGCT) are usually treated in an identical fashion as patients with recurrent testicular cancer. However, little is known about the long-term outcome in these patients and whether they have comparable results to patients with a testicular primary tumor. The purpose of this study was to evaluate the effect of salvage chemotherapy on long-term survival in patients with EGCT. MATERIALS AND METHODS: We conducted a retrospective review of 73 patients with relapsed extragonadal nonseminomatous germ cell tumors (GCTs) treated at Indiana University between 1976 and 1993. All patients received cisplatin-containing regimens as primary chemotherapy. RESULTS: Only five of 73 patients (7%) were long-term disease-free survivors after salvage chemotherapy. The remaining 68 patients are either dead of disease or toxicity (n = 63), or alive with progressive disease (PD) (n = 5). Twenty-eight patients received high-dose chemotherapy with autologous bone marrow transplant (ABMT) at some point during their disease, and none of these patients are continuously disease-free. CONCLUSION: Although similar salvage chemotherapy strategies will cure approximately 30% of patients with recurrent testicular cancer, new approaches are needed for EGCT.

Cerebrospinal fluid levels of amyloid beta-protein precursor are low in Gerstmann-Sträussler-Scheinker disease, Indiana kindred.

We studied levels of amyloid beta-protein precursor (beta PP) in CSF from four patients affected with Gerstmann-Sträussler-Scheinker disease and one asymptomatic gene-carrier from an Indiana kindred. Levels of beta PP were decreased in all affected patients with the lowest levels occurring in the clinically most severely affected patients. Correlation of neuropathology with CSF data in three patients suggested that low beta PP in CSF may be associated with beta PP accumulation in neurites surrounding cortical and cerebellar amyloid deposits.

Seasonality and children's blood lead levels: developing a predictive model using climatic variables and blood lead data from Indianapolis, Indiana, Syracuse, New York, and New Orleans, Louisiana (USA).

On a community basis, urban soil contains a potentially large reservoir of accumulated lead. This study was undertaken to explore the temporal relationship between pediatric blood lead (BPb), weather, soil moisture, and dust in Indianapolis, Indiana; Syracuse, New York; and New Orleans, Louisiana. The Indianapolis, Syracuse, and New Orleans pediatric BPb data were obtained from databases of 15,969, 14,467, and 2,295 screenings, respectively, collected between December 1999 and November 2002, January 1994 and March 1998, and January 1998 and May 2003, respectively. These average monthly child BPb levels were regressed against several independent variables: average monthly soil moisture, particulate matter < 10 microm in diameter (PM10), wind speed, and temperature. Of temporal variation in urban children's BPb, 87% in Indianapolis (R2 = 0.87, p = 0.0004), 61% in Syracuse (R2 = 0.61, p = 0.0012), and 59% in New Orleans (R2 = 0.59, p = 0.0000078) are explained by these variables. A conceptual model of urban Pb poisoning is suggested: When temperature is high and evapotranspiration maximized, soil moisture decreases and soil dust is deposited. Under these combined weather conditions, Pb-enriched PM10 dust disperses in the urban environment and causes elevated Pb dust loading. Thus, seasonal variation of children's Pb exposure is probably caused by inhalation and ingestion of Pb brought about by the effect of weather on soils and the resulting fluctuation in Pb loading.

Nutritional status of Northwest Indiana Hispanics in a congregate meal program.

Rapid growth in the Hispanic elderly population, coupled with their unique needs, necessitates increasing their numbers in Title III(C) meal programs. This study assessed the nutritional adequacy of the diets of 49 Northwest Indiana congregate meal participants by evaluating: (1) their 1-day food records, and (2) the contributions of the site meal to daily intake. Mean daily total nutrient intakes, except for energy intake by the men, exceeded 67% of the Recommended Dietary Allowances (RDAs); however, only 22% of individual diets met this standard. Mean site meal nutrient intakes, aside from energy and magnesium by men, exceeded the recommended one-third of the RDAs, and contributed 42-73% of most nutrients to the daily intake despite the fact that the majority of the recipients refused one or more offered site meal components. Results of this study verify the importance of the role of congregate meals in providing nutritional adequacy to diets of Hispanic elderly and can be useful in menu and program planning for this population.

Angel: post-implementation evaluation at the Indiana University School of Medicine.

With continued adoption of course management systems, librarians are assuming new roles and challenges with regard to providing information resources and library services in a digital environment. For approximately five years, the Indiana University School of Medicine has employed Angel as its online teaching environment, and the Ruth Lilly Medical Library has been actively involved in the adoption of Angel. As the implementation phase was completed, a post-implementation evaluation was due. The authors conducted an evaluation of the Angel system to evaluate utilization level, content types, and library resources/services integration. This article provides the findings of the post-implementation Angel Courses Evaluation.

Implementation of the Clinical Encounters Tracking system at the Indiana University School of Medicine.

The Indiana University School of Medicine (IUSM) Office of Medical Education &Student Services directed the IUSM Educational Technology Unit to develop a Clinical Encounters Tracking system in response to the Liaison Committee on Medical Education's (LCME) updated accreditation standards. A personal digital assistant (PDA) and centralized database server solution was implemented. Third-year medical students are required to carry a PDA on which they record clinical encounter experiences during all clerkship clinical rotations. Clinical encounters data collected on the PDAs are routinely uploaded to the central server via the PDA HotSyncing process. Real-time clinical encounter summary reports are accessed in the school's online curriculum management system: ANGEL. The resulting IUSM Clinical Encounters Tracking program addresses the LCME accreditation standard which mandates the tracking of medical students' required clinical curriculum experiences.

Effectiveness of the Indiana 4-H tractor program at instilling safe tractor operating behaviors and attitudes in youth.

The purpose of this research was to determine what impact the Indiana 4-H Tractor Program has had on safer tractor operating behavior and attitudes of participants and to provide recommendations for program improvement. To assess the impact, 108 non 4-H youth who reported they operated a tractor regularly were compared with 104 4-H Tractor Program participants. A single skilled evaluator observed each individual in the two groups as she/he operated a tractor through a standard tractor-operating course. Information on recent tractor-related injury history and attitudes toward tractor safety was gathered using a written survey. Results showed that the program has had both a perceived and demonstrable positive influence; however, a need for improvements was also shown. Most significant of the findings was that participants in the 4-H Tractor Program were observed to operate tractors in a safer and more skillful manner. Even though the 4-H Tractor Program participants reported substantially more exposure time to tractor operation, they did not report a significantly different injury experience in comparison to the non-participants. Responses from the 4-H program participants, however, indicated a trend toward having more tractor-related close call incidents. There was no significant difference between the two groups in their attitudes toward tractor safety. Program recommendations developed as a result of the study primarily related to the need for updating instructional material used in the 4-H Tractor Program and the need for additional training and resources for volunteer leaders.

The influence of habitat on the distribution and abundance of metacercariae of Macravestibulum obtusicaudum (Pronocephalidae) in a small Indiana stream.

Snails (Elimia livescens) from a central Indiana stream were examined for encysted metacercariae of Macravestibulum obtusicaudum (Pronocephalide) to determine the distribution and abundance of this parasite on its second intermediate host. Five samples of snails were collected, with 2 samples being restricted to high-flow (riffle) or low-flow (pool) areas of the stream. Snails (n = 386) were measured for shell length; the shell and the inner and outer surfaces of the operculum (in most samples) were examined for metacercariae. Seventy-five percent of snails (overall) had encysted metacercariae (range, 52-97%), primarily on the opercula. A significantly lower proportion of snails from riffles were infected, and these snails had significantly fewer cysts as well. Snails collected from pools showed up to 10 times as many metacercariae than those from riffles, although there was no significant difference in the proportion of snails with intramolluscan infections of M. obtusicaudum. The inner opercular surface appeared to be the preferred site of encystment in both flow regimes. Differences in microhabitats, in terms of both snails in the stream and metacercariae on the snails, clearly must be considered when evaluating the infection patterns of this trematode.

Comparison of virus neutralisation and enzyme-linked immunosorbent assay for the identification of antibodies against vesicular stomatitis (Indiana 3) virus.

Bovine, equine and swine sera from areas free from vesicular stomatitis virus (VSV) Indiana 3 (IND3)--namely Argentina, Chile, Italy and Uruguay--and endemic areas (in Brazil) were examined for anti-VSV IND3 virus antibodies in order to compare results obtained using the virus neutralisation (VN) test and liquid-phase blocking enzyme-linked immunosorbent assay (ELISA). Statistical analysis of the data showed close agreement between the two techniques (K = 0.92). The ELISA gave a higher specificity, positive predictive value and efficiency than the VN test. The ELISA offers the additional advantage of using a non-infectious antigen and can therefore be used for antibody quantification in diagnostic laboratories in VSV-free areas to support epidemiological surveillance programmes.

The pathogenesis of vesicular stomatitis virus, serotype Indiana, in Aedes aegypti mosquitoes. I. Intrathoracic injection.

Analysis of infectious virus particles after intrathoracic injection revealed that Aedes aegypti mosquito tissues are capable of supporting the growth of vesicular stomatitis virus (VSV), serotype Indiana. Although all tissues assayed (salivary gland, midgut, diverticulum, malphigian tubules, and ovary) were capable of supporting VSV growth, the salivary gland was the only organ capable of maintaining an appreciable amount of virus for periods longer than 9 days postinfection. Electron microscopic studies of infected tissues showed virus particles consistently within the cell cytoplasm of all organs with no evidence of nuclear involvement. Direct evidence of crystalline formation of VSV in the apical cavities of salivary gland tissue was demonstrated.

Virus-vector-host relationships of Aedes stimulans and Jamestown Canyon virus in a northern Indiana enzootic focus.

Collections of hematophagous Diptera at the Kingsbury State Fish and Wildlife Area in northern Indiana between 1982 and 1984 yielded 118,972 mosquitoes from which 5 isolates of Jamestown Canyon virus and 3 isolates of trivittatus virus were obtained. All Jamestown Canyon isolates were from Aedes stimulans, including 1 from a pool of newly emerged males and 2 from pools of newly emerged females. These 3 isolates suggest that Jamestown Canyon virus is transovarially transmitted by Ae. stimulans. All isolates of trivittatus virus came from pools of Ae. trivittatus. No isolates were obtained from greater than 4,000 tabanids collected along with the mosquitoes those years. Transmission trials with field-collected newly emerged adult female Ae. stimulans demonstrated a mean midgut infection rate of 44%, a disseminated infection rate of 16%, and an oral transmission rate of 12% to suckling mice. Precipitin tests of field-collected bloodfed female mosquitoes indicated that white-tailed deer were the preferred host for numerous mosquito species including Ae. stimulans. The results of this study suggest that Ae. stimulans is a primary vector of Jamestown Canyon virus and that transovarial transmission is the probable overwintering mechanism for this California group virus.

A human case of encephalitis associated with vesicular stomatitis virus (Indiana serotype) infection.

This paper describes a case of severe encephalitis in a 3-year-old Panamanian boy infected with the Indiana serotype of vesicular stomatitis virus. The virus was recovered from the child's throat on the fifth day of illness and a rise in neutralizing antibody titer was demonstrated in paired serum specimens. This is the second report of childhood encephalitis associated with vesicular stomatitis virus infection. These suggest that infection with vesicular stomatitis viruses may cause severe disease. Human infection with vesicular stomatitis viruses is common throughout the tropical Americas.

Canine distemper infection in pet dogs: II. A case-control study of risk factors during a suspected outbreak in Indiana.

The epidemiologic features of an outbreak of canine distemper during 1992 and 1993 in pet dogs in Indiana are described. Risk factors for disease were characterized using hospital records of private veterinary practitioners. The risk of disease for purebred dogs was 85% lower than the risk of disease for mixed-breed dogs. Lack of vaccination was associated with a 350-fold increase in the risk of canine distemper, and 93.8% of all cases could be attributed to the lack of vaccination. For many of the owners, the cost of medical treatment exceeded the cost of a vaccination program.
